Fuzzy Controller Structures Investigation for Future Gas Turbine Aero-Engines

Distributed Control Systems for Aero Gas Turbine Engines: A wicked problem for systems engineering?

Present day jet engines are controlled and monitored by a series of hydraulic, fueldraulic, electrical and pneumatic sub-systems known as the Full Authority Digital Engine Controller (FADEC). At the heart of the FADEC lies a centralised Electronic Engine Controller (EEC) responsible for control and safety of the wider engine system. It has long been postulated that a distributed EEC would contr...

Millimeter-scale, Mems Gas Turbine Engines

The confluence of market demand for greatly improved compact power sources for portable electronics with the rapidly expanding capability of micromachining technology has made feasible the development of gas turbines in the millimeter-size range. With airfoil spans measured in 100’s of microns rather than meters, these “microengines” have about 1 millionth the air flow of large gas turbines and...

Prognosis of Faults in Gas Turbine Engines

A problem of interest to aircraft engine maintainers is the automatic detection, classification, and prediction (or prognosis) of potential critical component failures in gas turbine engines. Automatic monitoring offers the promise of substantially reducing the cost of repair and replacement of defective parts, and may even result in saving lives. Current processing for prognostic health monito...

Performance Evaluation of Simple Aero Gas Turbine Cycle with Transpiration Cooling of Gas Turbine Blades

Aero gas turbine engines have been using mainly film cooling and convection cooling techniques. For operating at high gas temperature amongst different cooling options the transpiration cooling technique has emerged as the most promising technique to improve the gas turbine cycle performance by allowing higher turbine inlet temperatures. This paper investigates the advantages of transpiration c...
